Management of Elderly Patients with Sinus Rhythm and PVCs

Initial Evaluation and Risk Stratification

The American College of Cardiology suggests that an echocardiogram and 24-hour Holter monitor should be obtained to quantify PVC burden and exclude structural heart disease in elderly patients with sinus rhythm, occasional PVCs, and borderline ECG 1
If ≥2 PVCs are present on a single 10-second ECG tracing, this is considered abnormal and mandates further evaluation with 24-hour Holter monitoring 1, 2
The presence of a "borderline ECG" suggests additional findings beyond the PVCs that require investigation 3, 4

Echocardiography is required to assess for structural heart disease, particularly left ventricular hypertrophy, reduced ejection fraction, wall motion abnormalities, and dilated cardiomyopathy 1, 2, 3
24-hour Holter monitoring is required to quantify PVC burden and determine risk stratification 1, 2
A PVC burden <10% is generally benign in asymptomatic patients with a normal echocardiogram 1, 5

The American College of Cardiology recommends cardiology referral if any of the following are present: structural heart disease on echocardiography, PVC burden >10-15% on 24-hour monitoring, multifocal PVCs, wide QRS duration >160 ms on PVCs, non-sustained ventricular tachycardia, PVCs that worsen with exercise, symptomatic PVCs, or family history of sudden cardiac death 1, 2, 3

Primary care management is appropriate if the patient has isolated PVCs, a normal echocardiogram, PVC burden <10% on Holter monitoring, is asymptomatic, PVCs suppress with exercise, and has no family history of sudden cardiac death 1, 5

The American College of Cardiology advises against dismissing PVCs in elderly patients as benign without proper workup, as they may be markers of underlying structural heart disease 6
Antiarrhythmic medications should not be routinely prescribed for PVC suppression without cardiology consultation, as they can increase mortality in patients with structural heart disease 5, 2
